Sort of off topic, but I wanted to drop it out there.

I was trying to get my dad to download and run the Live CD a few days
ago, and he could not figure out what he was supposed to do with the
ISO. Of course, XP has no way to burn an ISO. And there are no
instructions on the site suggesting how to accomplish it.

He basically did as Paul said, dragged it to the CD burner software.

Wonder if there would be a good way to distribute a CD burner
application along with the .iso for Windows users.
